Without more information I think no one will be able to provide an answer.
What program are you using ?
I’m sorry. I am using Crystal reports. I had a report for my progress database. When we updated the database the new report definition does not contain one of the fields that our old report definitions uses. We do not need this field in our report, so I wanted to remove the field from the definitions, but I don’t see that option in Crystal Reports version 11.5
